  1. Open User Manager. From the Windows NT Start menu, select Programs, Administrative Tools (Common), User Manager.
  2. From the Policies menu, select Account to display the Account Policy dialog box.
  3. In the Minimum Password Length field, specify a minimum length of at least seven characters.
